OK Guys, my 2100fps load is with my personal weapon that has a highly altered timing point. You will not get even close to that fps area, before you hit the WALL, as I have described. The firearm will start short stroking well before you hit the pressure limit and it'll try to pull the rims off, all because it's trying to open way too soon. This is why, sometime soon, I'll be offering a retro-fit to your upper that will allow you to get past the "Timing WALL" and still be able to use the factory ammo, to boot.
Now, getting past the WALL, as I have described it, doesn't preclude you from using caution, in load development. This WALL is a kind of safety device, wherein, when you hit it, the pressures are still fairly low, the gun just doesn't function as it is supposed too. Once you go past the WALL, great things can be yours, if you practice good Safety Procedures, or you can wreck your gun or worst. In other words, once you get past the WALL, you've got no built in warning device (within reason, because you can still blow up the weapon, if you try hard enough) and reloading, for the 450b becomes just like any other normal weapon. You've got to do your part..
